Sodium benzoate SB is a white powder, used as preservative and food additive. Biochemical, physiological and histopathological effects of SB been tested in adult male rats. Twenty-four adult albino male rats aged100 day and weighted 250-350 g were used. Animals were divided into 4 groups. The first group considered as control, which received normal saline orally, other groups treated with SB by 300, 400, 500 mg/Kg of body weight respectively for 30 days. At the end of experiment, blood samples were collected from retro orbital sinus. Heart, liver, spleen, kidneys and brain were obtained for weight recording. The results indicated a significant decrease of super oxide dismutase SOD activity and a significant increase of nitric oxide NO level of treated group 500 mg/Kg of body weight. Moreover, findings revealed that there are no significant changes in growth hormone GH activity and body weight. A significant reduction of heart weight of treated group 500 mg/Kg of body weight were observed. The histopathological changes ranged from mild to severe in the brain cortex, as focal gliosis, satellitosis, mild vacculation and vasogenic edema in treated groups with SB by different doses. Also, some changes were observed in liver represented by congestion of portal vein, mild hydropic degeneration of hepatocytes, stenosis of sinusoids, steatosis and necrosis of hepatocytes in treated groups with SB compared to control group. It concluded that short-term exposure to high doses of SB may be considered an oxidant substance that caused oxidative stress. Furthermore, SB can harm various organs in the body.

Although ongoing control strategies are attempting to minimize certain metabolic disorders such as hyperketonemia, factors such as genetics, management, environment, and geography still present a potential challenge to the achievement of the desired results. In light of this, this study was conducted (i) to determine the prevalence of subclinical and clinical ketosis based on the concentration of ketone bodies (BHB) using ELISA Kit, and (ii) to examine a number of epidemiological risk factors related to the conditions. From October, 2020 to the January, 2021. A 80 blood samples were collected in a cross-sectional survey in different areas of Mosul. Data included age, management systems, parity, and origin. At the cut-off point ≥1.2-≤ 1.4 mmol / L, the prevalence of subclinical ketosis was 27.5% and for clinical ketosis it was 5%. Results revealed that the animals aged > 3 years were more at risk for subclinical ketosis compared to animals aged ≤ 3 years RR = 2.6471. Multiparous animals were more at risk compared to the primiparous (two or less births) RR = 2.0652. No significant difference between the animals’ origins RR = 0.6863. Indoor and outdoor system animals were more at risk for subclinical ketosis compared to the indoor system only RR = 2.1389. In conclusion, hyperketonemia is prevalent in Mosul. Certain risk factors should be taking into account when planning control programs. Attention should be paid to diagnosis, management, and control of this disease during the risk stage to avert economic loss to the dairy farmers.

The study’s aim was to examine the antihyperlipidemic effect of apigenin in mice as a model. Healthy adult albino mice of either sex were selected to use for this study. Four groups of animals were formed of 5 mice each. Animals Group 1 served as a negative control and fed the standard diet and tap water. Groups 2,3 and 4 were fed fatty diet and 1% water with H2O2 for 90 days to induce hyperlipidemia. After hyperlipidemic induction, group 2 served as a positive control, whereas group 3 was treated orally with apigenin 50 mg/kg/day for 14 constitutive days. Group 4 was treated by rosuvastatin (an antihyprlipidemic drug) orally at 7 mg/kg for 14 constitutive days. Blood samples were collected from all of the animals at the beginning of the study to measure the lipid profile. Then these were rechecked again after 12 weeks of feeding a high-fat diet, and then at the end of the experiment for the treated groups. The results demonstrated that the apigenin at 50mg/kg significantly reduced hyperlipidemia manifested by decreased TC, LDL-C, Triglyceride and elevation of HDL-C in comparison with the positive control group. The results, obtained by apigenin were the in accordance with those of the standard drug rosuvastatin for TC and LDL-C. This study concluded that apigenin lowered plasma cholesterol and triglycerides levels in mice.

The present study was conducted to compare the total white blood cells count, granulocytes and phagocytic activity in female rats immunized with lipopolysaccharide (LPS) extracted from two different isolates of Escherichia coli, one normal isolate from the gut of healthy adult and the other was pathogenic strain isolated from patients suffering from urinary tract infection. The study was included 35 female albino rats divided randomly into seven groups, three groups injected with different concentrations of LPS of normal flora of E.coli 90, 120 and 150 microgram/kilogram body weight respectively and the other three groups were injected with the same concentrations of LPS extracted from pathogenic strain of E.coli, the last group (7th) represented the control group which given normal saline only. The results showed that the LPS from normal isolate causes a significant increase in the total number of leukocytes, granulocytes and phagocytic activity in animals immunized with the concentration of 120 µg/kg compared with the control group, and the concentration of 150 µg/kg of the same extract resulted in a high significant increase in phagocytic activity and the concentration of 90 µg/kg did not stimulate any significant differences in all the variables, while immunization with the extract of pathogenic strain increases the total leukocytes at a concentration of 90 µg/kg only with a significant increases in phagocytic activity at all concentration, and it also did not cause any significant differences in the granulocytes count.

The present study aims to clarify corneal development via analyzing of the histomorphologic and some histochemical parameters in local rabbits. Samples were collected from 25 Rabbits divided into five different age groups at 1, 10, 15, 30, and 40 postnatal day (PND), then the samples sectioned, processed, and stained with Hematoxylin and eosin stain and Masson’s trichrome stain. Some sections were further stained with periodic acid Schiff (PAS) and toluidine blue (TB) stain for histochemical evaluation. Measurements of corneal layers performed for morphometric comparison among age groups. The finding revealed thickening of corneal epithelium, stroma, and corneal endothelium progressively with age and decrease of corneal layer’s cellular density concurrently with alteration of corneal epithelium and corneal endothelium cell’s type. The histochemical finding revealed late appearance of bowman’s and Descemet’s membranes after eyelid opening which responded strongly to PAS technique while stroma became metachromatic strongly responded to toluidine blue stain. In conclusion, cornea showed highly active histological development and cellular differentiation before and after eyelid opening.

The purpose of the current experiment was to test the immunization against Coenurus cerebralis in sheep. Sixteen animals (6 months old, from 1 October 2020 to 30 March 2021 in Najaf city) were recruited to perform the experiment, in which eight of them were injected twice at 21-day interval using the cellular metabolic antigen of C. cerebralis protoscolex cultivated and then emulsified by complete Freund's adjuvant (CFA). The shots were injected intramuscularly at a dose of 1 ml (15 mg of antigenic protein determined in a separate experiment). The second group of eight sheep served as controls (injected intramuscularly with 1 ml sterile saline only at the days of injections). Blood samples were collected from all animals at day-0 (before injection) and at day 10, 18, and 24 after the first injection, and at day10, 16, 26, 40, 48, 53, 61, 80, 85, and 89 after the second injection. Serum activity was studied by indirect enzyme-linked immunosorbent assay (iELISA). The findings, by iELISA, revealed that the cellular antigen of C. cerebralis protoscolices is an active stimulator of antibody response. Day-10 (after the first injection) showed significantly (P<0.05) 3.4 to 9.9 time-higher antibody levels compared to those from day-0. This elevation in the titer of antibodies was increased after receiving the second dose showing 6.3 to 12 time-higher antibody presence even at the final days of blood collection compared to those from day-0. No changes were noticed in the sera of the control animals. The obtained data allow us to conclude that metabolites synthesized by cultivation are active immunogenic components that activate the humoral part of the immune system manifested by the increases in the antibody titers. This gives a solid ground for future work regarding alternative methods of discovering immunization techniques against cestodes.

This study aimed to isolate and characterize extended-spectrum ß-lactamases (ESBLs) and AmpC producing E. coli in sheep in Mosul city. A total of 260 milk and fecal samples were collected aseptically from healthy ewes (n=60), their respective lambs (n=60), and ewes with clinical mastitis (n=40). Standard bacterial isolation and identification on special culture media were performed to isolate ESBL/AmpC producing E. coli. While special antibiotic discs D68C MASTDISCS® Combi AmpC and ESBL ID set were used to characterize positive ESBL/AmpC E. coli. The results showed that 99/260 (38.1%) of tested samples were ESBL-E. coli positive and distributed as follows, 7/60 (11.7%) and 39/60 (65%) from milk and feces of clinically healthy ewes, respectively, and 37/60 (61.7%) from feces of clinically healthy lambs, while 4/40 (10%) and 12/40 (30%) from the milk and feces of ewes with clinical mastitis, respectively. However, we could not obtain any AmpC positive isolate from all tested samples. The high recovery percentages of ESBL from feces or milk of sheep reflect the arbitrary use of the antibiotic in sheep farming. This could significantly increase the resistance of the bacterial population that might represent a potential source for transmission of antibiotic resistance to humans.

We aim in the current study to investigate the pathology and incidence of tumors that are excised surgically in Veterinary Teaching Hospital. This study collected the tissue samples from animals from 1 October 2020 until 1 April 2021. These samples were collected from animals that undergo surgical procedures to remove neoplastic growths in their body. After tissue grossing, samples were collected from tumor mass, then fixed in neutral buffered 10% formalin for 72 hours, then processed to embedded in paraffin wax. A routine Harris’s hematoxylin and eosin stain were also used, histochemical stains such as Masson’s trichrome and PAS techniques were used as needed. In exceptional cases, IHC protocol was used for diagnostic steps to some types of tumors included in the current study. The antibodies that were used are Vimentin for canine osteosarcoma, P53 for squamous cell carcinoma, Mdm2 for ovine pulmonary adenocarcinoma, and CD10 for neoplastic lymphocytes. The result of the current study showed that the prevalence of tumor recorded was Marek’s diseases 22.8%, squamous cell carcinoma 22.8%, ovine pulmonary adenocarcinoma 15.4%, third eyelid adenoma 15.4%, canine osteosarcomas 7.4%, venereal transmitting tumors 7.4%, and feline mammary gland tumor 7.4%. Histological examination of feline mammary gland tumor composed from server infiltration of neoplastic cells, these neoplastic cells identified as lymphocytes in a fibrous stroma. Third eyelid adenomas in cats and dogs were composed of well-demarcated nodules containing neoplastic sebaceous cells present in glandular form and combined by hyperplasia of epidermis extended inside the neoplastic mass. Venereal transmitting tumor in cat composed from cells with a round to oval shape and the cytoplasm is poorly defined by routine stain, with dense fibrous tissue. Osteosarcoma in a dog has a pleomorphic nature with an anaplastic form composed of islands of osteoid materials, and the tumor is composed of three types of osteoblast, chondroblast, and fibroblast. Pulmonary adenocarcinoma in sheep composed of a nodular formation containing dense collagen fiber deposition with transformation of cells lining alveoli into cuboidal or columnar cells can also be observed in other air passages. Squamous cell carcinomas are primarily found in skin lesions associated with the formation of pathognomic lesions known as keratin pearls. This lesion is composed of the acentric layer of keratin produced by neoplastic keratinocytes. Marek’s disease was observed in visceral organs such as liver, lung, kidney, intestines, and spleen composed from pleomorphic lymphocytes, diffusely proliferating small-to-medium-size lymphoblast. In conclusion, the incidence of tumor in animals that attending Veterinary Teaching Hospital belong to the College of Veterinary Medicine, the University of Mosul was in general high in comparison to other studies in Iraq and other countries, this high incidence should pay attention to the causes of these cancerous conditions and their relation to environmental etiology.

The current work was carried out during the period from September, 2020 to March, 2021 in Mosul city, Iraq, with the objectives to detection of canine distemper virus (CDV) for the first time in Mosul using microscopic examination of blood smears, rapid serum antigen test and sandwich ELISA test as well as determine the agreement between the different diagnostic methods. A total of 92 blood samples were collected from suspected dogs with CDV (69 stray dogs and 23 Pet dogs). A primarily detection of CDV in blood smear by the presence of inclusion bodies in erythrocytes and leukocytes, followed by detection of CDV antigen in serum using rapid test and sandwich ELISA test. Results indicate that the infection rates of CDV in dogs were 32.6%, 13%, and 19.5% using microscopic examination, rapid test and sandwich ELISA test respectively. A statistically significant higher infection rate was reported in stray dogs compared to pet dogs based on all diagnostic tests used in this study. Based on Kappa values 0.413, 0.675, 0.745, there were moderate agreement between microscopic examination and rapid test, and substantial agreement between microscopic examination and sandwich ELISA test, also between rapid test and sandwich ELISA test respectively. In conclusions, CDV is widespread in dogs in Mosul city, Iraq and all tests used in this study are efficient for detection CDV based on compatibility between them.

The Aim of study was conducted to evaluate the potential protective role of quercetin against the corneal toxicity which caused by administration of cisplatin in male mice. Thirty-six adult male albino mice were divided into three equal groups; Group I control, Group II cisplatin mice injected as single dose I.P of cisplatin 10 mg/kg, and Group III mice received Q 75 mg/ kg with cisplatin 10 mg/ kg. The treatment continues for eight days then the tissues were collected for histopathological study. The histopathological changes in the cornea of eye were demonstrated in groups of mice received cisplatin. The changes represented by damages of superficial epithelial layer, vacuolar degeneration, hyperplasia, separation of stromal layer and sever damage of the stromal hemorrhage, and perforation of sclera, edema and inflammatory cells infiltration as well as separation of descement membrane from stroma layer. While these changes were diminished when the mice are treated with Q in the combination of cisplatin in comparison to treated cisplatin alone mice. Cisplatin induced structural and histopathological changes in the cornea of adult albino rat that could be ameliorated by concomitant treatment with quercetin.

No former studies are dealing with the pharmacological (pharmacodynamics and pharmacokinetics) interaction between nefopam and tramadol in the chicks' model. The median effective doses (ED50s) for nefopam and tramadol produces analgesia has been estimated each alone as 9.24 and 0.83 mg/kg, IP, respectively. The interaction concerning nefopam and tramadol combination was estimated by isobolographic analysis to be 2.91 and 0.25 mg/kg, IP. The kind of interaction between nefopam and tramadol was synergistic as indicated by the interaction index 0.61. The analgesic efficacy of the combination was significantly different from nefopam and tramadol administered alone. Nefopam plasma concentration 18.48 mg/kg, IP for different measured times 0.5, 1, 2, 4, and 24 hours 33.25, 27.10, 15.05, 13.61, and 2.45 µg/ml while the concentration was increased once coadministered with tramadol 1.66 mg/kg, IP by 22, 26, 43, 45, and 81% been 40.72, 34.27, 21.53, 19.76, and 4.43 µg/ml, respectively. Nefopam pharmacokinetic profile comprised of area-under-curve (AUC), area-under-moment-curve (AUMC), mean-residence-time (MRT), half-life (t1/2β), maximal concentration (Cmax) amplified after tramadol is coadministered with nefopam by 52, 260, 23, 15, and 22%. The elimination constant (Kel), distribution volume (VD), clearance (Cl) were diminished 13, 25, and 29%, similarly. The sum results suggested a synergistic interaction between nefopam and tramadol along with a modification in nefopam pharmacokinetic parameters which improve the therapeutic efficacy of nefopam in the chickens besides, advocate using these two drugs as preanesthetics in veterinary medicine.

Bacterial contamination of milk and dairy products is a common problem. In the last two years, the foodborne diseases caused by the intake of milk and dairy products have been mostly disturbed with Salmonella entertica, Listeria monocytogenes Escherichia coli 0157:H7 and Campylobacter jejune. The study aims to isolate multidrug resistance (MDR) bacteria in dairy products and study of the molecular characterization of that isolates. MDR bacteria were found in 30 out of the 131 bacterial isolates. The incidence of MDR bacterial isolates revealed the abundance of Staphylococcus sp. with 43.3%, Bacillus sp 16.7%, Salmonella 13.3%, E. coli 10 %, Enterococcus 6.7 % Psedoumonas 3.3 %, Shegella 3.3 % and Proteous 3.3 %. Molecular studies of genes presence or absence for class A contain TEM, CTX and BSHV, class B contain VIM, IMP, KPC and NDM, class C contain FOX and class D contain OXA-10, OXA-24 and OXA-58 were tested. NDM, TEM, CITM and OXA -10 genes were the most abundant the selected bacterial isolates. The results of this study indicate that cheese made from unpasteurized milk can pose a significant risk to consumers. Product manufacturing processes should be subject to health control-to-control pathogens. The novelty in this work depend on screening of gene responsible of the resistance from the bacteria isolated from dairy product using the molecular technique.

Bluetongue virus (BTV) is an arbovirus, causes bluetongue (BT) disease of ruminants responsible for mortality and trade limitation. The objective of this study was to provide a descriptive review analysis of global research activity for the period 2000 to 2020. The number of articles, temporal evolution, geographical distribution, countries, funding agencies, authors, research theme, and the source was analyzed and presented in visualization maps. Search query resulted in 3878 documents from 5681 authors, and 2017 articles were analyzed. The annual number of publications showed a steep increase from 2005 to 2020 related to attention to BT as an exotic disease in Europe, as well as the interest in vector over-distribution due to climate change. Most of the studies were performed in Europe, followed by Asia and North America. The top active countries in article production were the United Kingdom and the United States. A considerable international collaboration network of the UK with the USA and European countries was observed. However, the collaboration was weak with Asian and African countries. The major research themes are genomic viral studies, the role of Culicoides as a vector, serological and molecular epidemiology, and vaccination. In conclusion, an increase in scientific production and international collaboration was noticed during the last two decades. However, international collaboration needs more attention to African, and South American countries. The current study provides useful references for the policymaker, academics, animal health professionals, and funding agencies to follow the past and except the future BTV themes.

Titanium dioxide nanoparticles have multiple beneficial uses, as they are used in many medical, industrial, economic, and other fields. Despite these many benefits, it is not without harm to humans and animals if used without control. Therefore, the present study aimed to discover the histopathological effects of Titanium dioxide nanoparticles on the liver of Japanese quail, Coturnix coturnix japonica. The study included three groups, the first group, the control group, which were dosed with distilled water for four continuous days, and the second and third experimental groups, which were dosed with Titanium dioxide nanoparticles at a concentration of 20 and 40 mg/kg, respectively. Four, fourteen, thirty and sixty days after the experiment began, the birds were sacrificed. The results showed the emergence of many histological lesions in the liver of birds of the two experimental groups, to varying degrees, in the four periods, among the most prominent tissue lesions that appeared in the second experimental group, the emergence of necrosis, hemorrhage, vacuolation, congestion, ballooning swelling, in addition to infiltration of inflammatory cells. While in the third experimental group, histopathological lesions appeared similar to second group, in addition to sinuses dilatation, Kupffer cells hypertrophy, hepatocyte enlargement, and necrosis of the walls of blood vessels and bile ducts. The study concluded that direct exposure to Titanium dioxide nanoparticles leads to damage to the liver tissue of these birds, which may affect its function and thus endanger its life.

Retention of placenta (RP) is a failure of the fetal membrane to be expelled and remained from 8 to 48 hours, average 12 hours after parturition. There are a variety of risk factors for the occurrence of RP. So, the aim of this study was to quantify the relative risk of calving season, parity, and gestation length on the occurrence of RP, and assess the impact of RP on the subsequent reproductive parameters, and the economic losses. A data of 2940 purebred Holstein-Friesian cows were collected from reliable records of large commercial dairy farm, Sharkia governorate, Egypt. These cows calved during the period extended from January 2018 to December 2019. Cows that did not release the fetal membranes within the first 12 hours after calf expulsion were diagnosed with RP. Results of logistic regression analysis revealed that the important risk factors for the occurrence of RP were summer calving season and short gestation period. Odds ratio estimation for summer calving season compared to spring calving was 2.84. The probability of RP incidence in cows with shorter gestation period was 0.19 times more than cows with longer gestation length, and the total direct economic losses from RP was 47 $/cow. Finally, we can conclude that short gestation length and summer calving season are strongly correlated with the development of RP in dairy cows. Subsequently, the occurrence of RP significantly affects reproductive parameters resulting in economic losses in dairy herds.

The study aimed to explore the ameliorative effects of silymarin when administered with flunixin on the liver, kidney, and blood components in rats. The animals were divided into four groups; each one consists of five rats. The first group was served as a control. The second and third groups were treated with silymarin 200 mg/kg b.wt, p.o and flunixin 2.5 mg/kg b.wt, i.p respectively. The fourth group was treated with silymarin and flunixin concurrently. The involved rats were treated for seven consecutive days by a single daily dose. Following the treatment, the biochemical analysis ALT, AST, ALP, Urea, and Creatinine, blood analysis parameters RBC, HGB, HCT, WBC, and PLT, and a histopathological examination liver and kidney were studied for the involved animals. The results showed that flunixin increased the levels of ALT and AST and the concentrations of Urea and Creatinine, and the total number of WBC. Also silymarin caused a remarkable decrease in the flunixin adverse effects on the liver and kidneys. This was reflected from the histological features observed from the diverse tested groups. Based on these findings, the authors concluded that silymarin has the ability to reduce the harmful effects of flunixin on both the liver and the kidneys.

Cows are considered as reservoir hosts for many pathogenic bacteria that are resistant to broad-spectrum beta lactamase(ESBL). Presence of ESBL resistant K. pneumoniae in nasal of cows and beef meat constitutes a risk for public health due to transfer of antibiotic resistance gene from cows to environment, humans and farm animals. Therefore, the current study was concluded the detection of molecular characteristics of ESBL producing Klebsiella pneumoniae that was isolated from both cow's nostrils and from local beef samples. Fifty nasal swabs were collected from farms cows in Mosul city, and 50 samples of beef from local butcher shops for the period from February to August 2020. Bacterial isolation and identification tests were conducted for ESBL resistant Klebsiella pneumoniae using MacConkey agar medium with-1 μg/ml cefotaxime. PCR was carried out to confirm the results using special primers (SSKP 1 F and SSKP 1 R) for Klebsiella (the target gene 16srRNA). Then, a molecular examination was performed using the precursors CTX-M, TEM and SHV. Through bacterial isolation, 36 (72%) and 28 (56%) isolates were belonging to ESBL resistant Klebsiella pneumoniae from nasal samples and beef meat respectively. The CTX-M, TEM and SHV genes formed (100, 89.2, 85.7) % and (100, 72.2, 71.4) % for each the meat and nasal samples respectively. This study showed that cows play a major role in transferring ESBL producing Klebsiella pneumoniae from cows to humans as a result of environmental handling or consumption contaminated meat.

The aim of this study was to identify and diagnose of M. haemolytica strains as one of the most important causes of ovine clinical mastitis in Mosul city. One hundred and thirty-three milk samples were directly obtained from the udders of ewes infected by clinical mastitis from November 2020 to January 2021.Standard and conventional methods were followed for isolation and identification of M. haemolytica. Milk samples were cultured on blood agar 7% and MacConkey agar, then it was purified and was stained by Methylene blue. Later, different biochemical tests were Conducted. Molecular identification of M. haemolytica depending on 16srRNA gene, followed by sequencing, similarity and phylogenetic tree was generated. The results showed that 62(46.61%) of samples were positive for bacterial isolation, biochemical tests and conventional PCR technique. Sequencing results showed that the positive samples were belonged to M. haemolytica strains. The similarity within strain Ib001 and within strain 39433 were 100%, and 99.47% respectively. Poor management was associated with the high level of mastitis caused by M. haemolytica, so the application of prophylactic programs should be followed to limit the spread of the disease.

Globally, extended-spectrum ß-lactamase (ESBL)/Ampicillin ß-lactamase (AmpC) producing Escherichia coli has become the greatest threat for distributing antibiotic resistance. Accordingly, this study was designed to detect and screen the genes that confer resistance in E. coli isolated from sheep as main livestock in Mosul city. Forty E. coli isolates previously recovered from milk and fecal samples were included in this study. These isolates were obtained from healthy ewes, their lambs, and also from ewes with clinical mastitis. Polymerase chain reaction (PCR) was used to confirm the E. coli isolates targeting the 16sRNA gene. Furthermore, screening of different genotypes of ESBL/AmpC was conducted using specific primers. The results showed that the CTX-M gene was predominant among ESBL genotypes and recorded 40/40 (100%). While, SHV and TEM genes recorded 7/40 (17.5%) and 5/40 (12.5%), respectively. Moreover, fecal carriage of resistance genes was more than that obtained from milk in both healthy and diseased animals. However, none of the 40 isolates showed positive results for AmpC genes. The presence of different genotypes of ESBL E. coli isolated from feces or milk origin may act as a potential source for transferring antibiotic resistance to humans, other animals, and the environment.

This study investigated the effects of orlistat and rosemary extract on kidney tissue when combined with a high-fat diet, as well as the association between these treatments and body weight, blood lipid profile, and oxidative stress status in male rats. 42 rats weighing 170-200 grams were divided into seven groups, each consisting of six rats. The experiment lasted 20 weeks and was divided into two phases: a stage of induced obesity using high-fat food (fattened), which lasted from week 0 to week 12, except for the control group, which was fed a normal diet. The treatment period lasted from week 12 to week 20, with daily dosing, and the totals were distributed as follows: the first control group was dosed with distilled water alone, the second group was fed a high-fat diet only, the third group was given rosemary aqueous extract at a 10 ml/kg, the fourth group was given orlistat at a dose of 100 mg/kg, the fifth group was given orlistat at a dose of 200 mg/kg, and the sixth group was given orlistat at a dose of 100 mg/kg as well as extract. The seventh group received orlistat at a dose of 200 mg/kg and the extract. When compared to the high-fat diet and the rest of the groups, the weights of the animals increased significantly, as did the lipid profile like TC and LDL, TG, and VLDL in the blood, which were accompanied by decrease in the levels of glutathione and increase malondialdehyde. When given a high-fat diet and orlistat, histopathological examination of the kidneys revealed changes in the renal tissue, including glomerular atrophy, necrosis and cloudy swelling of epithelial cells lining renal tubules, whereas when given the extract with orlistat, these effects were reduced. We conclude that rosemary aqueous extract has preventive and therapeutic antioxidant properties, as evidenced by its improved effect on the histopathological changes induced by orlistat drug in kidney tissue, as well as its improving effect on the state of oxidative stress in the kidney tissue and the level of lipids profile in the blood, and its weight-loss efficacy.

This study was aimed to prepare bacterin toxoid from local isolate of methicillin resistant Staphylococcus aureus (MRSA) isolated from bovine mastitis in Basrah province. Isolated MRSA was detected and confirmed using polymerase chain reaction. Then inactivated bacterin toxoid was prepared. A total of 45 male albino rats were used in 3 mainly groups to assess the bacterin toxoid. For immunological response, the concentrations of IL-4, CD4+, and CD8+ T-cells were estimated using enzyme linked immunosorbent assay. The results showed increase in the concentrations of IL-4, CD4+ and CD8+ T-cells in vaccinated group comparing with non-vaccinated control group. Increasing concentrations of IL-4 enhance humoral immune response by stimulation of Th2 that effect directly on B-cells differentiating them to plasma cells responsible for production of specific antibodies against MRSA. Increased CD4+T-cells also enhance humoral immune response as a result of interaction between them and antigen-presenting cells which presented major histocompatibility complex (MHC) type II on their surface, while increased CD8+T-cells enhance cellular immune response as a result of interaction between them and somatic effected cells presented MHC type I on their surface leading to differentiation them to Cytotoxic T lymphocytes (CTLs) responsible for the killing of effected cells. It was concluded that locally prepared bacterin toxoid proved their efficacy to stimulate both humoral and cell mediated immunity in rats as an experimental animal model.

Bovine hypodermosis has been known as a veterinary disease that mainly caused by Hypoderma bovis and Hypoderma lineatum. This study aimed to determine sero-prevalence of cattle grubs in Mosul, Iraq utilizing indirect ELISA as well as effect of some risk factors on prevalence of hypodermosis. A total of two hundred blood specimens were collected from healthy and infested cattle through direct palpation. All samples were collected from cattle at Teaching Veterinary Hospital, Mosul abattoir, Kokjali and Bazwaya region during October 2020 to March 2021. Outcomes of iELISA showed 40.5% as an infestation rate of hypodermosis. Notably, infestation intensity has distributed as light, moderate and sever 11, 18.5 and 70.3% respectively. Interestingly, highest seroprevalence of hypodermosis was recorded in October 67.7%, and the lowest was recorded in February and March 22.2%, 25% respectively. Observations of current study also recorded the infection rate in age was 54.7% in animals less than 3 years old, and the lowest was 16% in animals more than 3 years old. Moreover, breed showed a significant risk factor 53.8% for imported cattle and 14.7% for local breed. Importantly, risk factor concerning area recorded the highest rate in Kokjali 52.2%. In contrast, the lowest rate recorded in Teaching Veterinary Hospital 14.8%. The present study is the first investigation to identify cattle hypodermosis by iELISA in Mosul, Iraq. iELISA has been approved as the best diagnostic tool for early detection of hypodermosis during the migrating phase. Interestingly, age, breed and months of study were significant risk factors.

The present study was designed to estimate the effect of carrots supplementation on reproductive performance in ewes. Thirty Awassi ewes. Ewes were randomly divided into three equal groups, distributed as 10 ewes for each group. First group consider as control, second group feed 400 g carrot/animal daily, third group feed 800 g carrot/animal daily. Each group were synchronized with intra vaginal sponges and injected with 400 IU of eCG at the time of sponge withdrawal. Estrus ewes were conceived naturally with rams and pregnant ewes were followed until parturition. The results of current study demonstrated that G3 had high estrus response and fertility rate 90% compared with G2 and control 80 and 70% respectively. Fecundity rate increased significant in G3 200% compared to G2 and 125 and 100% respectively. Ewes in G3 showed the highest multiple lambing rate 66.67% compared with G2 25% and control 0%.

Food additives and preservatives are widely used globally, which, despite their many benefits, have great harm if they are used without health restrictions or control, as they cause many health problems and tissue lesions. Therefore, the present study aimed to investigate the histopathological effects on the lung of pregnant rats of two types of these substances: Monosodium glutamate (MSG) and Sodium nitrite (NaNO2). Twenty-four pregnant rats used for this study, and they were divided into four groups equally. The control group was dosed with distilled water from the sixth day to the fifteenth day of pregnancy. The second was dosed with MSG at a 12g /kg concentration for the same period in the first group. The third injected with a concentration of 120 mg/kg of NaNO2 for the same period. The fourth was dosed with MSG and NaNO2 together, with the same concentrations and the above period. The results showed that the second group's lungs showed many histopathological changes, including strong infiltration of inflammatory cells, congestion of blood vessels, necrosis of bronchioles and alveolar septa, and emphysema of some alveoli. In the third group, changes included hyperplasia of the fibroblasts, hemorrhage in the alveoli, desquamation and necrosis in bronchioles, peri-bronchial fibrosis, blood vessel congestion. The fourth group showed infiltration of inflammatory cells, necrosis in multiple lung areas, emphysema, fibrosis in some alveoli, and hypoplasia of the muscle fibers around the blood vessels. The study concluded that MSG and NaNO2 caused much tissue damage in the lungs of pregnant rats.

The efficiency of fresh Aloe vera gel was tested on the healing of large cutaneous wounds of the forelimbs in donkeys. Twelve adult donkeys from both sexes were used in this experimental study. They were divided into equal groups. A square shape cutaneous wound about 8*8cm, was induced on the lateral aspect of the forelimb exactly between humeral and knee joint. In group one, the induced wound was left without treatment, while in second group the wound was treated by local application of fresh Aloe vera gel. The evaluation of healing process results was based on monitoring the gross signs of wound healing, in addition to the study the histopathological changes at 15th, 30th, 45th postoperative days. In group one, the wound healing process was characterized by infection, congestion, inflammatory exudate, excessive granulation tissue formation, and no decrease in wound size, while in group two, the healing of wound was characterized by absence of granulation tissue overgrowth with decrease in wound size and little occurrence of infection and congestion. The histopathological observations in first group was showed intensive granulation tissue formation with massive infiltration of mononuclear inflammatory cells and delay of reepithelization, while in second group, overgrowth of granulation tissue was lesser, little infiltration of mononuclear inflammatory cells, rapid reepithelization with more maturation and stretching of collagen fibers. It was concluded that the Aloe vera gel can be used successfully as topical treatment to improve and enhance large cutaneous wound healing in donkeys.

A challenge to the orthopedic surgeons in veterinary and human fields is the treatment of delayed union, malunion and nonunion. Apart from renovation of arrangement and constant fixation, in many cases, adjunctive measures such as bone-grafting or the use of bone-graft substitutes, are of dominant significance. In general bone-graft materials comprise one or more components: an osteoconductive matrix, which acts as a scaffold to new bone growth; osteoinductive proteins, backing the mitogenesis of indistinguishable cells; and osteogenic cells, which can form bone in the proper environment. Our review focuses on the currently existing bone graft and graft substitutes for the novel therapeutic approaches in the clinical situation of orthopedic surgery. This review is based on an extensive literature search of different composite scaffolds developed as bone regenerative therapies. The settlement and drawbacks of different composite scaffold developed techniques, the properties of generally used ceramics and polymers, and the properties of presently investigated synthetic composite grafts. To follow, an exhaustive review of in vivo models is used to test composite scaffolds in segmental bone defects (SBDs) to serve as a guide to design suitable translational studies and to recognize the challenges that require to be overcome in scaffold design for successful transformation. This includes the formative of the anatomical position within the animals, selecting the accurate study period, and an overview of scaffold presentation evaluation.

In this study, we examined blood samples of 385 sheep and goats of different ages, sexes, and sources under routine microscopic examination of the blood smear (wet, thin, thick, buffy coat layer smears) to detect Trypanosoma. Results show that 81 samples were positive. These samples are succumbed to the molecular detection of Trypanosoma and other species by the extraction of parasitic DNA This parasitic DNA is detected in samples using KIN1, KIN2, and AITSF, AITSR primers. After that, Conventional Polymerase Chain Reaction was applied, and the results showed that 81 samples had a positive reaction in using KIN1 and KIN2 primers, while the positive samples were 76 when using AITSF, AITSR primers. Moreover, results showed a high rate of infection in sheep as compared with goats using both pairs of primers and two species of Trypanosoma in sheep and goats. Molecular was recorded, which include T conglense and T vivax. Animals more than 1-2 years old group showed a high rate of infection as compared with other ages group, and females have recorded a high rate of infection as compared with males. According to the source of animals, imported animals showed a high infective rate compared to native ones. This study is the first recorded Trypanosoma species in small ruminants in Mosul city.

This project evaluated the effects of nano magnesium oxide versus platelets rich fibrin on induced radial fracture bone healing. Eighteen males and nonpregnant females of adult local stray dogs, weighing 17.6±0.85 kg and aged 2.08±0.13 years, were used. These trials animals were randomly divided into three groups of equal numbers. In the first group, Control group (C), a transverse radial fracture was induced then immobilized by external fixation as gypsum. In this group, the fracture line was not treated with any bioactive material. In the second group, platelets rich fibrin group (PRF), the fracture line was treated by adding platelets rich fibrin. In the third group, nano magnesium oxide (NMO), the fracture line was treated by adding a suspension of nano magnesium oxide. The radiographic results showed that the fractured bone healing was faster in the second group than in the first and third groups, while the third group was better than the first group. The concentration rates of serum calcium and alkaline phosphatase were increased in the weeks followed the surgical operation. Depending on the radiographic pictures and serial rates of alkaline phosphatase, the second PRF and the third NMO groups were the better-fractured bone healing than the first one. In conclusion, this study revealed that using each platelets rich fibrin and nano magnesium oxide enhanced and improved the healing of the induced radial fracture.

In the present study, the effect of autogenous peritoneum graft (PG) with platelet rich fibrin (PRF) was evaluated on intestinal anastomosis healing in dogs. Eighteen local breed adult dogs were anesthetized then jejunal intestinal resection and anastomosis were created on all animals. Animals were divided into 3 equal groups (6 for each). In first group (control): An end-to-end intestinal anastomosis was performed using simple interrupted suture pattern only. In group PG: The anastomosis site was sutured as in control group and was wrapped with PG. Where as in PRF+PG group: The anastomosis site was sutured also as in first group and was wrapped with PRF and PG. Healing process was studied in all above mentioned groups clinically, grossly, histologically and radiographically at 15 and 30 days post operation. Results were revealed that the utilizing of PG caused a valuable influence on anastomosis site healing. This impact was manifested by faster re-epithelization of mucosa, increased collagen deposition, fibroblast proliferation, reduced adhesions, and decreased stenosis degree comparison with control group. Also there was less adhesions, less stenosis degree, increased in epithelization of the mucosa in the group treated with PRF+PG than the group treated with PG alone. In conclusion the current study has shown that autologous peritoneal graft application has a positive and beneficial effect on intestinal anastomosis healing. Also the results highlighted the promising effects of PRF in conjunction with PG on intestinal anastomosis healing. The application of PRF with PG at the intestinal anastomosis site is successful, safe, and highly efficient with no complications.

Microscopic histological examination discovered generalized congestion of blood vessels at the cerebrum and cerebellum, degeneration and necrosis of the neuronal cells of the cerebral cortex which characterized by swelling of the degenerative cells, while necrotic cells characterized by shrunken and pyknosis of the cells in the cerebellum cortex presents of inflammatory cells in the meninges. In conclusion, the histopathological examination of brain sections of rabbits treated with ethylene glycol in addition to Urtica dioica extract showed slight improvement in the histological pictures of the cerebellum and cerebrum.

The present study provides new insight into valuable information on the diverse structure of the anisakid population, discusses the limited species richness, and also discusses the relationship with other closely diversity-related taxa in NCBI databases in the Epinephelus diacanthus and Epinephelus coioides fish. The fishing area consists of various locations in the Arabian Gulf. A total of 69 E.coioides and E. diacanthus were examined, (n= 48) were infected. Larval stages (n=1,119). Isolated larvae were encysted within the mesenteries peritoneum and viscera of fish organs, with a prevalence of 81.25% of infection and 59.459 % in the E. diacanthus and E. coioides respectively. Molecular analysis was carried out on thirty individuals of nematode parasites who have examined the morphology and showed some appearance differences, by amplifying internal transcribed spacers ITS and ITS-1 of nuclear rDNA (rDNA) by PCR using the primer sets NC5/NC2 and SS1/NC13R of DNA products. Evolutionary analyses were conducted in MEGA X. based on the identity percentage in the GenBank database showed that they belong to anisakid nematodes, in particular, they belong to nine distinct taxa within the Hysterothylacium spp. The presence of the same species individuals in one host may be the cause of these genetic variations at the species level, and that's what the current study has recorded. It has been found that there is an overlap in the order of nitrogen bases between the same species, and this occurs through the fertilization process, while the rest is clean or have only a few parasites.

The objective of this project was to study the induction of smooth anesthesia characterized by good induction (hypnosis), analgesia and good recovery with mild side effects caused by drugs. The effect of using Ketamine with both xylazine and midazolam KXM was investigated in adult rabbits and compared with the positive control group that was administered with ketamine alone K at 40 mg/kg i.m, and with ketamine - xylazine group KX at 40 and 4 mg/kg i.m respectively, and with ketamine - midazolam group KM also at 40 and 4 mg/kg i.m respectively. Administration of xylazine and midazolam each one alone at 4 and 2 mg/kg I.M induced analgesia in a dose-dependent manner through a significant elevation of the electrical voltage after injection when compared with its value before injection. A minimum doses of a mixture KXM at 20,2 and 2 mg/kg i.m respectively, induced good hypnosis with rapid induction and long duration with recovery periods without significant variations in vital physiological parameters (respiratory rate, heart rate, and rectal temperature) and some biochemical parameters (GPT and GOT and glucose level) comparing with groups K, KX and KM. The outcomes of this work were revealed to the induction of proficient general anesthesia that was described by effective hypnosis with analgesic efficacy throughout the administration a minimum doses of ketamine/xylazine/midazolam combination in rabbits.

The study aimed to (ⅰ) examines whether quantitative and qualitative digital analysis of hepatic ultrasound images can be used to detect fatty liver and grading its severity, (ⅱ) to estimate the concentration of serum β-hydroxybutyrate content in normal and diseased animals. A total of 50 buffaloes (15 clinically normal and 35 suffered from decreased milk production, loss of appetite, and loss of body weight) 2-4 weeks after parturition were studied. Buffaloes were examined by real-time ultrasound using a 3.5 MHz convex probe. Ultrasound images were saved for qualitative and quantitative analysis, using computer aid Fatty-Liver software (programmed in Matlab language). Based on the digital analysis of ultrasound images, the diseased buffaloes were classified as mild (n=20), moderate (n=7) and severe (n=8) fatty liver affection. Results indicated that the concentration of β-hydroxybutyrate estimated via ELISA were 0.409, 0.735, 0.923, 1.708 mmol/dL in normal, mild, moderate, and severe diseased buffaloes respectively. However, a significant difference has been encountered among normal and diseased animals. It has been concluded that buffaloes at Mosul suffered from fatty liver and digital analysis of ultrasound images was a suitable method for clinical diagnosis, furthermore, estimation of β-hydroxybutyrate was a suitable method for laboratory diagnosis.

Cyclophosphamide (CP) is a cytotoxic alkylating drug that is commonly used to treat autoimmune disorders and cancer. CP causes nephrotoxicity by producing highly reactive radicals devoid of oxygen. A fat-soluble vitamin E that interacts as a free radical scavenger, inhibiting nitrosamine production and blocking lipid peroxidation from polyunsaturated fatty acids. The aim of this research was to see if vitamin E may help combating CP induced nephrotoxicity. Thirty-two adult albino female Westar rats were randomly divided into four groups (n=8) and received daily treatment for thirty days. Group A considered as control group, receiving normal saline IP at dose of 0.3 ml, group B given 15 mg/kg b.w. of cyclophosphamide IP, while group C received cyclophosphamide with vitamin E at dose 200 mg/kg, oral administration of vitamin E one hour before injection of cyclophosphamide, in group D they received vitamin E orally at dose of 200 mg kg body weight mixed with olive oil daily by oral gavage. In group B the cyclophosphamide causes highly significant reduction in body weight and histologically showed atrophy of most glomeruli, distention in bowman’s space, tubular degeneration and luminal hyaline cast material, while in group C showed most of the glomeruli normal except atrophy of few number of glomeruli and focal epithelial degeneration of renal tubules. Our study found that one of the primary mechanisms induced by cyclophosphamide may be nephrotoxicity due to oxidative stress, and pretreatment with vitamin E reduces cyclophosphamide-induced nephrotoxicity.

Herbal products are increasingly used against lipid to attenuate its negative impact on vasculature system. However, there are uncertainty regarding the best administration approaches and preparation of herbal product to be used due to variation in absorption rate and extent with subsequent impaction on the lipid levels. The aim of the present study was comparing the pharmacological and analytical aspects of soaked versus powder form of Hypericum perforatum; a well-known anti-hyperlipidemic herbal product, using atorvastatin drug as a reference drug for comparison in addition to controlling groups (on/off lipid diet) handled as an additional control group. To conduct this research, the hyperlipidemia mice models were created by exposing the mice to a fatty diet and using H. perforatum and atorvastatin for evaluation. The plant extracts were also analyzed for active constituents. The results indicate that the plant analysis detected the presence of different antihyperlipidemic agents and the plant has effectively reduced plasma lipid parameters in exposed mice compared to control group; especially when taken forms of the plant was used. The study concluded that; soaked H. perforatum extract shown an effective reduction of lipid parameters and analysis of which revealed the presence of herbal active constituent which might be utilized in industrial pharmacy for new drug innovation.

This study aims to characterize different Salmonella enterica subsp molecularly. enterica strains (n=49) were isolated from human gastrointestinal cases in the Tolima region and poultry from Santander and Tolima regions using PCR-RFLP, PCR-ribotyping, and PCR-SSCP. The band patterns obtained with each technique were analyzed by building dendrograms based on the Unweighted Pair Group Method with Arithmetic mean (UPGMA) method and using the Dice coefficient. On the other hand, the discriminatory power of each technique was assessed using Simpson's discriminatory index. The genetic profiles of the gnd gene obtained with AciI restriction enzyme and the PCR-SSCP carried out with groEL gene allowed the inter-and intraserovar differentiation. Finally, the PCR-ribotyping method exhibited the highest discriminatory power (0.8571). In conclusion, we show three PCR-based genotyping methods providing an alternative for identifying similarities and differences within Salmonella enterica strains from different geographic and biological regions.

The susceptibility of lambs to infective diseases should be minimized by improving the immunity of lambs through effective vaccination procedures to abate lamb mortality in sheep farms. In this regard, field experiments were carried out with 180 pregnant ewes of Naeemi sheep breed at the PAAFR (Public Authority for Agriculture and Fisheries Research Station, Kuwait). The results revealed that the concentration of serum Ig’s in blood samples collected from ewes vaccinated during pregnancy with Pasteurella, Clostridia, FMD (Foot and Mouth Disease) and PPR (Peste des Petits Ruminants) vaccines was significantly elevated as vaccination against these four diseases agents would have ultimately resulted in circulating antibodies protecting the animals against natural exposure. The concentration of colostral Ig’s produced by vaccinated ewes during the pregnancy period was significantly (P<0.05) higher than the normal colostrum secreted from unvaccinated ewes during pregnancy, ensuring the positive role of the colostrum in transferring passive immunity. The results clearly illustrated no cases of mortality and abortion, as vaccination has played a role in maintaining the health of ewes by overcoming the targeted pathogens and preventing any abnormalities in the pregnant ewes. The present study confirmed the improved immune status of young lambs born to ewes vaccinated twice during pregnancy, reflecting improved health status. It is recommended to maintain 21 days’ intervals in vaccinating ewes with different vaccines for specific diseases.

The concentration of colostral Ig’s produced by vaccinated ewes during the pregnancy period was significantly (P<0.05) higher than the normal colostrum secreted from unvaccinated ewes during pregnancy, ensuring the positive role of the colostrum in transferring passive immunity. The results clearly illustrated no cases of mortality and abortion, as vaccination has played a role in maintaining the health of ewes by overcoming the targeted pathogens and preventing any abnormalities in the pregnant ewes. The present study confirmed the improved immune status of young lambs born to ewes vaccinated twice during pregnancy, reflecting improved health status. It is recommended to maintain 21 days’ intervals in vaccinating ewes with different vaccines for specific diseases.
